Jab/2 F Longer PATENTEDJUL 3 1915 I 3.743; 12 l v John E Lan gerUNLOADING CHUTE ASSEMBLY AND MEANS DETACHABLY CARRYING SAME ON A VEHICLEThis invention relates to chutes for unloading trucks and the like.

It is therefore the primary purpose of this invention to provide ahydraulic loading chute transport which will be carried by the trailerso that it will be readily available for unloading the trailer at itsdestination.

Another object of this invention is to provide a chute apparatus whichwill be operated by hydraulic means to affect the proper positioning ofthe chute member and raising and lowering the legs of the device.

Another object of this invention is to provide a chute apparatus whichwill have a main frame portion in which will be mounted the motor andpump means for operating the hydraulic cylinders to lower or raise thewheel portions and also to lift the chute portion to any desired angle.

A further object of this invention is to provide a chute apparatus ofthe type described which will have locking means for rendering the wheelportions stationary in the upward and downward position.

Other objects of the present invention are to provide a hydraulicloading chute transport which is simple in design, inexpensive tomanufacture, rugged in construction, easy to use and efficient inoperation.

These and other objects will be readily evident upon a study of thefollowing specifications and accompanying drawing wherein:

FIG. 1 is a side view of a tractor trailer combination showing theinvention in its carried position while in transport;

FIG. 2 is an enlarged side view of the invention shown in elevation;

FIG. 3 is a side view of the invention showing it removed from thetrailer with the leg portions shown in their lowered position and alsoshows a chute member lifted;

FIG. 4 is a view taken along the lines 4-4 of FIG. 2;

FIG. 5 is a crosssectional view taken along the lines 5-5 of FIG. 4; and

FIG. 6 is a fragmentary and enlarged view taken along the lines 6-6 ofFIG. 4.

According to this invention, a hydraulic loading chute transport 10 isshown to include brackets 11 of L-shaped configuration which are fixedlysecured to the underside 12 of trailer 13.

Brackets 11 serve to support hydraulic loading chute transport 10 whilethe trailer 13 is in transport.

Hydraulic loading chute apparatus 10 is shown to include also, a hollowrectangular frame 14 which carries an enlongated chute member 15 whichis hingeably secured by end 16 to frame 14.

A hydraulic cylinder 17 is secured to a bracket 18 pivotably and bracket18 is fixedly secured to a crossbar member 19 of chute 15. The oppositeend of hydraulic cylinder 17 is pivotably secured to a bracket 20 on theunderside of frame 14.

Hydraulic cylinder 17 serves to raise and lower chute member 15 to anydesired angle for unloading the trailer 13.

A second hydraulic cylinder 21 is pivotably secured to frame 14 at oneend and is pivotably secured to a bar 22 which is pivotable at pin 23 ofa central cross bar 24 of frame 14.

Arms 25 secured to bar 22 are pivotly secured to arms 26 extending offof shafts 27. The arms 26 are fixedly secured to shafts 27 and when thehydraulic cylinder 21 is actuated, will pivot the plurality of legs 28upward or downward depending upon the desire of the operator.

Pivotably attached to legs 28 are caster wheels 29 which enableapparatus 10 to be placed in any desired position.

A pair of levers 30 and 31 provide control means for apparatus 10through the motor and hydraulic pump arrangement 32 carried within frame14.

In use, the legs 28 and their attached wheels 29 are lowered by means ofhydraulic cylinder 21, and when they are fully lowered and locked,apparatus 10 will clear the support brackets 11 of trailer 13 and thusallow the operator to roll the apparatus 10 to the loading site.

The chute member 15 is then raises to any desired position by means ofthe hydraulic cylinder 17.

What I claim is:

1. An unloading apparatus for use with a vehicle having bracket means onthe underside thereof for carrying and transporting such apparatus, saidapparatus comprising a frame, parallel shafts journalled on oppositesides of said frame and having supporting legs extending radicallytherefrom, a bar pivotally attached at its center to the center of saidframe and extending generally parallel to said bar, link means connectedrespectively to opposite ends of said bar and said shafts such thatpivoting of said bar will rotate said shafts and extend or retract saidsupporting legs, caster means carried by said legs, actuator means forpivoting said bar, a chute pivotally connected at one end thereof tosaid frame, whereby upon extension of said legs the apparatus may berolled free of said brackets to a suitable position relative to thevehicle and the chute may be pivoted to an inclined position to receivegoods from said
